Trump attacks China in Twitter outburst
“Did China ask us if it was OK to devalue their currency” and “build a massive military complex?” he asked. “I don’t think so!”
China said both sides should “stick to basic principles” of the relationship.
Last week Mr Trump risked a diplomatic rift with China by speaking directly with Taiwan’s president.
The highly unusual move saw China lodge a complaint with the US.
In response to the latest tweets, without directly referring to them, the Chinese foreign ministry said the US and China have long had “highly mutually beneficial” relations.
A spokesperson declined to comment on “he and his team’s method and what’s the thinking behind it”, referring to Mr Trump.
The US has previously criticised China’s yuan devaluation, saying it unfairly favours Chinese exporters.
It has also told Beijing to stop reclaiming land around islands and reefs which are claimed by multiple countries in the South China Sea, and has sent US Navy ships to the area. Both sides have accused each other of “militarising” the region.
Mr Trump’s phone call with Taiwan’s President Tsai Ing-wen was thought to be the first time a US leader or leader-in waiting has spoken to a Taiwanese leader since 1979, the year formal ties were severed.
The White House has said the phone call did not signal a shift in its decades-long “One China” policy stance, which does not recognise Taiwan as an independent sovereign state but also does not recognise Beijing’s claim over Taiwan.
Vice President-elect Mike Pence has tried to downplay the call, saying it was a “tempest in a teapot” and “a moment of courtesy”.
Beijing lodged a “solemn representation” with Washington, where it urged the US to “cautiously and properly handle” the issue of Taiwan, according to Chinese state media.
Beijing sees Taiwan as a province and aims to deny it any of the trappings of an independent state. It has threatened to use force if Taiwan formally declares independence.
